IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. 127,161, dated May 281872; antedated May 11, 1872.

To all whom it may concerns Be it known that I, FRANK FIGHT, ofMarinette, in the county of Oconto and State of Wisconsin, have inventeda new and Improved Automatic Lubricator; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art'to make and use the same,reference being had to the accompanying drawing forming part of thisspecification.

Figure 1 is a vertical section. Fig. 2 is aside elevation. Fig. 3 is ahorizontal section.

Similar letters of reference indicate corresponding parts.

A is a cup or body of the apparatus; B, a cock or valve for regulatingthe flow of the oil or lubricant. G is a stem, with valve and hand-wheelattached, passing down through the center of the apparatus to thevalve-seat e at the bottom, said valve being used for the purpose ofstopping the flow of the oil. D is a guide for said valve 0, also aguard, to prevent dirt or sediment from entering into the passage Ethrough the holes Tin said guard, the holes being placed a little abovethe bottom of said cup A that the sediment may lodge outside. E is apassage for the oil to flow down into the cylinder, steam passage, orwhere it may be required. F is a globe-valve to admit steam into the cupA, or shut off the same, when required, through the steam-passage g andtube It, said tube extending nearly to the top of cup A and above theoil, as indicated by the dotted lines in the drawing. 'i is a cock tolet out the steam remaining in the cup after the other valves have beenclosed and before refilling with oil. K is a cover to passage L, throughwhich the cup is filled with oil or other lubricant. M is a glass set inthe side of the cup A or apparatus, for the purpose of inspecting theoil in it. N is a dialplate. 0 is a hand secured to the regulating cockor valve to indicate the position of said cock or valve, or the openingit presents for the flow of oil.

To adjust this improved lubricator for operation, I close the valves 0and F, open the cock 1' and cover K, then fill the cup A with oil evenwith the top of the glass in the side of the apparatus, then close theopening or passage L with the cover K, also close the cock t. Next, Iopen the valve 0, allowing the steam to blow through the passage E andholes T, clearing them of any sediment or dirt that may have lodgedthere, depositing it outside the guard D. Then I open the valve F andlet the steam pass up through the passage g and tube h to the top of theoil and create an equal pressure on the top of the oil with that in thesteam-passage below. The oil will then flow down through the passage Eby its own gravity into the steam-passage, in such quantity as may bedesired, by adjusting the regulating-cock B.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- An automatic lubricating apparatus, consistin gessentially of the cup A provided with a cover, K, cock '5, and glass m,the stem 0 with its valve and hand-wheel, the guide D with its openingsT, the valve B, oil-passage E, globe-valve F, steam-passage g, and tubeIt, all arranged and operating together, as and for the purposedescribed.

FRANK FIGHT.
